PORTABLE FIRE-EXTINGUISHER.

Specification of Letters Patent.

Patented March 31, 1908.

Application filed April 5, 1906. Serial No. 310,053.

'10 fire extinguishers which are adapted for instant use, can be used by one person to throw a stream of water or chemical fluid on a fire. The ob ect 'of my invention 1s to secure the highest resistance by the tank to internal 5 pressure combined with the lightest material to combine the filling with both air and fluid to the same aperture in the tank; to increase the force of the stream by air pressure; to combine the outlet and discharge nozzle, and to reduce the cost of the extinguisher.

The manner in which I accomplish my objectis described in the following specification. and illustrated in the accompanying drawings, in which! Figure 1 is a central vertical sectional view ,of the extinguisher, with all its parts in their itelative positions. Fig. 2 is a View of the nozzle se arated from the discharge valve.

In the raWings A is a tank constructed of ab suitable material, size and shape.

of the tank 'a is preferably of cylindrical form having an aperture a near the bottom for the discharge, and a flange a at the bottom edge and a curved flange a at the tpp edge. Engaged in this top flangeis the top B of the tank this is convex in outward form and provided with a handle 'b which is riveted to the top by rivets b-. The

. circular edge ofthis top is flanged to form a 0 channel .b Thisfchannel isadapted to receive the flangededge of the body of the tank. These flanges are a'l'lixed together by a body of solder 't", the partsbeing well sweated together. The bottom C of the tank is conical in form having a flat top and a central a )erture -a-. This bottom is adapted in diameter to fit the interior ol" the body of thetank and to rest on a ring c* which rests onthe bottom flange -,-a of the body of the tank and is a'HiXed to the interior of said body. The external and internal joints formed by this body of the tank, flange, ring and bottom are strengthened by wire rings, c and by 65 bodies of solder c which are sweated The body into these parts. The ring c-- and the conical shape of the bottom places the center of the bottom some distance into the interior of the tank. In theaperture -c a flanged 'bushingc is aflixed by a body of solder csweated into the bottom (.3 and the bushing; The interior of this bushing is threaded and forms part of a valve D through which the tank is filled. Screwed into this bushing is the body Z of the valve, the shoulder '-d ofv this part is under cut and. with the bottom of the bushing forms a V shaped space between these parts. In this space is a lead ring .d

adapted to'iit the V shape and under ressure this ring is forced inward\on to the t readed part thereby forming aperfect air and water tight oint.

- Through the center of the part d' is a passage way d 'On' the eXternal-threaded end d* is a cap d containing a leadv gasket "d adapted to close the passageway -(Z and to orm a perfect air and water, tight joint. The length of the part -dand the cap is ada rted to bring the bottom of the cap within the-base line of the bottom flange on the body part of the tank. In the interior of the tank thepart d of the valve is in the iorm of an extended neck d and a head d Through this head are twovertical holes -d", adapted to hold pins 'd which are adapted to be moved in them. Affix'ed to the ends of these pins is a cap d Attached to this cap by these ins is rubbergo disk -d adapted to cover t e head d and to form a valve to open and close the pas; sage way (2 The movement of this Valve is limited by the heads on the pins d which are adapted to engage the underside of .the head d 'In the interior of the body of the tank. and registering with the aperture therein is a flanged ring I this ring is permanently affixed to the tank and forms a support for the dischargevalve connections. Afl'ixed tothis ring in the interior of the tank is a perforated cylindrical strainerF. Supported in the flanged ring E and in the aperture a and on the body of the tank is a Hanged bushing -.G having a threaded part g and a central passage way g Fitted on to this bushing is a cylindri a1. extension -g'- having a central a turc g, and chamber 'g*.. This aperture is threaded and adapted to support a nozzle 11o ing and close the hole therein.

The threadedend h'--has a slot h and is adapted to extend into the chamber g" In this chamber is'a valve I consisting of rubber disk J adapted to cover'the end of the bush- Aflixed to this disk is a metallic cap K secured to the disk by screws L; This cap is somewhat larger in diameter than the end -h of the nozzle, which is adapted to engage it and to force it and bushing.

, What I claim as new and desire to secure by Letters Patent is:

1. In a fire extinguisher of the kind described the combination comprising atank having a cylindrical body flanged attop and bottom, a top flanged into the top of said body,a ring sugported on the bottom flange inside of said ody and aflixed thereto; a conical bottom affixed on said ring and. in

said body; a combination water and air valve affixed in the apex of said bottom, said valve consisting of a bushing, a member insertible in said bushing, a compressibe ringadapted to form a joint between said'bushing and member, a movable valve on the end of said member in said tank, and a cap on the external end of said member; a discharge valve in the side of said main body, consisting of a bushing, a chamber supported thereon, a valve in said chamber, and a nozzle supportedv in said chamber adapted to close said valve.

2. In a fire extinguisher of the kind de-- scribed the combination with a sheet metal tank consisting of a flanged body and flanged top affixed in said main body of a conicalsha ed bottom extending upward in said tan said bottom being joined to said main body and supported on a ring aflixed inside said main body and bottom flange thereon;

and a discharge valve affixed in said main body of said tank consisting of a fixed bushing, a cylindrical extension having an internal chamber and ada ted to be su ported on said, biishin a va ye adjust'ab e in said chamber and a nozzle supported in said extension and adapted to engage and close said valve substantially as described and for the purposes specified. I

,3. In a fire extinguisher of the kind described the combination'with a sheet metal tank consisting of a flanged body, a flanged top joined thereto, a bottom aflixed therein and conical in form; of a combined Water and air valve affixed in said bottom, said valve consisting of a main body afiixed in said bottom and having a central aperture extending into said tank, an externa cap adapted to close the outer end of said body and aperture therein, and a valve adjustably supported on the internal end of said body ada ted to close the inner end of said aperture; an a dischar e valve affixed in said tank, and an adjustab e nozzle supported in said valve adapted to open and close said discharge valve, substantially 'as described and for the purposes specified.

4. In a fire extinguisher of thekind de .scribed the combination of a tank having fixed; top and bottom, said bottom bein conical in form, and a combined water an air valve affixed in said bottom; with a discharge valve affixed in said tank, said valve consisting of a flanged bushing affixed in said tank, a chambered cylindrical extension attached to said bushing and having a threaded aperture adapted to support a nozzle, a valve movable in said chamber in said extension, and a threadednozzle, sup orted in said extension, having a slotted en said slotted end being ada ted to engage and close said valve in saic chamber, substan-' tially as described and for the purposes speci-. fied.

5. The combination with the bottom of a fire extinguisher, of the kind described; of a combined water and air valve, one of the members of said valve being affixed in said bottom, the face of said member having an inward bevel, the main body of said valve being insertible in said fixed member, and having a shoulder beveled inward and forming together with the beveled face of said fixed member an annular-V shaped channel, the bottom of said channel forming the base of'the angle; and a lead ring adapted to fit in said channel and to form a removable waterand air tight joint, substantially as described and for the purposes specified.
